ASTM A179 Seamless Cold-Drawn Steel Tube Heat Exchanger & Condenser Tube

Product Introduction & Standard Specification

The ASTM A179 / A179M Seamless Cold-Drawn Low-Carbon Steel Tube is a premium-grade tubing specifically engineered for high-efficiency heat transfer applications. This specification covers seamless, cold-drawn tubes with a minimum wall thickness, making them ideal for constructing reliable and compact heat exchangers, condensers, and similar thermal equipment.

The standard applies to tubes with outside diameters ranging from 1/8 inch to 3 inches (3.2 mm to 76.2 mm). It's important to note that mechanical property requirements do not apply to tubes with an outside diameter smaller than 1/8 inch [3.2 mm] or a wall thickness under 0.015 inches [0.4 mm]. This product conforms to the latest ASTM A179/A179M-24 standard and often meets the complementary general requirements of ASTM A450/A450M.

Material & Manufacturing Process

This tube is manufactured from low-carbon steel using a seamless process, ensuring there are no welded seams that could be potential failure points under thermal cycling and pressure. The final dimensional accuracy and enhanced mechanical properties are achieved through a cold-drawing process. The steel is produced under controlled conditions, with both heat (melt) analysis and product analysis performed to guarantee chemical composition conformity.

Chemical Composition & Mechanical Properties

The chemical composition is tightly controlled to ensure optimal weldability, formability, and corrosion resistance. A typical optimized composition for high-performance tubes is shown below.

Element	Content (%)
Carbon (C)	0.06 - 0.18
Manganese (Mn)	0.27 - 0.63
Phosphorus (P)	≤ 0.035
Sulfur (S)	≤ 0.035

The cold-drawing and subsequent heat treatment give the tubes excellent mechanical properties, often exceeding the minimum standard requirements for strength and ductility.

Property	ASTM A179 Requirement
Tensile Strength	≥ 325 MPa (47 ksi)
Yield Strength	≥ 180 MPa (26 ksi)
Elongation (in 2 inches or 50 mm)	≥ 35 %

Key Features & Testing

To guarantee integrity, every tube undergoes a series of stringent tests as per the standard:

Hydrostatic Test: Verifies pressure tightness and strength.
Flattening Test & Flaring Test: Assess ductility and the ability to withstand forming without cracking.
Hardness Test: Ensures material consistency.
Non-Destructive Electric Test: Often performed (e.g., eddy current) to check for imperfections.
Surface Condition: Tubes are supplied free of scale, with advanced options like pickling and passivation available for a superior surface finish (e.g., Ra ≤ 0.8μm) that improves heat transfer and corrosion resistance.

Product Applications

ASTM A179 tubes are the material of choice for critical heat transfer surfaces across industries:

Power Generation: Condenser and feedwater heater tubes in fossil-fuel and nuclear power plants.
Oil & Gas / Petrochemical: Heat exchangers, coolers, and condensers in refineries and chemical processing plants.
Marine Industry: Shell-and-tube heat exchangers for engine cooling and other shipboard systems.
HVAC & Refrigeration: Components in industrial cooling systems and evaporators.
Industrial Boilers: As boiler tubes where high thermal conductivity is needed.
